After consulting with ModBargains’ Modification Experts to determine the best fitment for his needs, Aaron went with a square 19×9.5 ET39 front and rear, and opted for the silver finish. He then chose to wrap the CF5V’s in 255/35/19 Hankook Ventus V12 tires to give the S4 a nice flush fitment without any rubbing or brake clearance issues.

This is because despite the deep concavity, the rotary flow-formed Forgestar CF5V was designed to clear big brakes like the S4’s and utilizes the same advanced wheel construction technology utilized in Formula 1 and IndyCar racing, meaning they’re up to the task of going to the track. Aaron certainly puts his wheels to the test, too, check out the pictures below of Aaron taking his Audi S4 going hard at a local Autocross event.
